Side & Rear Flail Operation Section 3-5
OPERATION
To ensure a clean cut, engine speed should be maintained at approximately 1800
– 2200 R.P.M. If the tractor slows to less than 1800 R.P.M., shift to the next lower
gear. DO NOT ride the clutch, this will cause premature clutch failure. The engine
should not be operated at any time at more than 2400 R.P.M. on the tractor
tachometer.
The mower will operate more efficiently in tougher conditions and with less power
if the knives are kept sharp. If the mower begins to vibrate, stop the tractor, check for
wire wrapped in the spindle or damaged knives. When replacing knives, replace all
knives with new knives to ensure proper balance so the mower will not vibrate.
Severe vibration will result, if knives with unequal wear are used. Follow the
instructions in the maintenance section closely when replacing knife blades.
If bystanders approach within 300 feet while mower is in operation turn
mower switch “OFF” immediately! After shutdown, never leave the
tractor or allow bystanders to approach within 300 FEET of the unit until all
motion stops completely.
When encountering a very severe condition which causes the tractor to stall,
disengage mower, start tractor, raise the mower from the cut. Shut tractor off and
inspect the mower, blades and disk for damage before engaging mower again.
If the blades jam or stop, disengage the clutch and raise the head slightly or back
the tractor up. Normally, this will clear the cutter head. If not, shut off the mower(s),
raise the cutter heads, turn off the tractor and set the parking brake. After all motion
stops completely, leave the tractor and clear the cutting heads manually.
After the first day of operation, all bolts should be checked and tightened
securely.
This should be done periodically to ensure the bolts do not become loose and cause
damage to the tractor or mower, or injury to the operator.
